lb all whom it .may concern.-

Be it known that I, WARREN H. VREE- LAND, a citizen of the United States, residing at Seneca Falls, in the county of Seneca, in the State of New York, have invented new and useful Improvements in Carpenters Gages,

of which the following is a specification.

This inventlon relates to gages for laying out and marking the mortises for butt-hlnges and for analogous purposes.

an elevation of a gage embodying the inven- .tion, showing the same in operative pos1t1on against a part, such as a door or door-jamb, for marking the hinge-mortise. Fig. 2 is an end elevation thereof.

Fig. 4 is a longitudinal sec- Fig. 5 IS a fragmentary section, on an enlarged scale, in line 5 5,

Fig. 1. Fig. 6 is a section in line 6 6, Fig. 5.

Like letters of reference refer to like parts .in the several figures.

The gage comprises two parallel arms A and a connecting body portion or plate B, to

which the arms are adjustably connected to be moved and secured nearer to or farther from each other, as required. The outer edges of the arms are parallel with each other and at right angles to the outer longitudinal edge of the connecting-plate The latter is a rectangular plate or piece provided in its rear or under side with a longitudinal guide groove or channel 1), into which project and slide lonitudinal guide-ribs b on the front or top faces of the arms, which latter are also preferably provided with longitudinal guide shoulders on their front or top faces, which slidably bear against the inner longitudinal edge of the connecting-plate. The end pieces are thus heldin exact parallelism with the connecting-plate in their different adjustments.

C represents clamping-screws, which Work in holes in the arms and extend through longitudinal slots 0 in the connecting-plate and are provided with milled heads or finger- Fig. 3 is a rear elevaa pieces, which bear against the connectingplate to secure the arms in adjusted positions. by other means. They are provided, pref erably on their front or upper faces, with graduations (Z, which cooperate with the opposite ends of the connecting-plate to indicate the length of the gage or distance be tween the outer edges of the adjustable arms.

E E represent adjustable bearing-blocks which are located on the rear or under sides of and proj ect out from the adjustable-arms to bear against the edge of the door, doorjamb, or other part with which the gage is to be used and which are adjustable lengthwise of the arms of the gage. The bearing blocks have screw-threaded stems extending through guide-slots e in thearms of the gage to which they are clamped in ad usted positions by clamp or thumb nuts F, screwed on said stems and adapted to bear against the front or top faces of the gage-arms. The stops can be moved in the slots of the arms and secured at the desired distance from the outer longitudinal edge of the gage, and the arms are provided on their under or rear faces with graduations f to enable the stops to be set for a mortise of known width without the use of a separate gage or rule. The bearing-faces of the stops are preferably convexed or rounded so that they will slide smoothly on the work.

The gage is provided with an adjustable marking device G, which is preferably carried by one of the bearing-blocks-for instance, the block Efor indicating the depth of the mortise. This device consists of a screwthreaded shank which extends through a longitudinal hole in the stem e of the bearing block E and a marking-point g, which projects out laterally through a slot 9 in the bearing-block. (See Fig. 5.) The end of the shank of the marking device projects out beyond the end of the stem of the bearingblock and is provided with an adjusting-nut h, which bears against the end of the stem of the bearing-block. When this adjusting-nut is loosened, the marking device can be moved lengthwlse of itself or transversely of the arm until the nut engages the end of the stem of The arms can be guided and secured the bearing-block, and then by turning the nut the marking device can be drawn in the opposite direction to properly position its marking point. For securely holding the marking device in the position to which it is adjusted the end of the stem 6 of the bearing-block is split, as at is, Fig. 6, and is tapered and externally threaded, and a clamping-nut K is screwed on this tapered threaded end of the stem. By tightening up the clampingnut the split end of the stem is contracted about the shank of the marking device, so as to grip and securely hold the latter. This construction is desirable, as it enables the adjustment of either the bearing-block or the marking device without disturbing the adjustment of the other part. Other means could be employed, however, to adjustably gage-arm a distance equal to the desired depth of the mortise. The gage is then placed on the face of the door, door-jamb, or other part to be cut, with the bearing-blocks against the edge of such part, as shown in Figs. 1 and 2, and lines are drawn along .the

longitudinal and end edges of the gage, after which the gage is moved along the edge of the door or amb, so that the'markingoint makes a scratch or mark indicating the epth of the mortise. As the marking-point is directly opposite the slot in the gage-arm on which it is mounted, themark made by thepoint will terminate at the marks on the face of the door or jamb whichindicate the ends of the mortise, if the movement of the gage is arrested when such end mark appears beneath the slot in the arm of the gage, and it is not necessary to unduly mar the work in the use of the gage. The gage can be uickly and easily set to mark mortises of different dimensions and is a very desirable device for rapidly marking. two or more mortises of the same dimensions.

I claim as my invention 1. The combination of a plate, an arm adjustab'ly secured to said plate to be adjusted lengthwise of the latter, a bearing-block adjustablelengthwise of said arm, and a marking device adjustable transversely toward and from the'face of saidarm, substantially as set forth.

2. The combination of a plate, arms extendingat right angles to and adjustably secured to said plate to be adjusted toward and from each other, bearing-blocks adjustable lengthwise on said arms, and a'marking device which is adjustable lengthwise of one of said arms and also transversely toward and from the faceof said arm, substantially as set forth.-

3. The combination of a plate, an arm projecting from andadjustable lengthwise of said plate, ,a bearing-block adjustable on said arm toward and from said plate, and-a marking device carried by said bearing-block and adjustable transversely of thedirection of adjustment'of the block and having a mark ing portion which extends in a direction substantially parallelwiththe direction of adj ustment of said bearing-block, substantially as set forth.

4. The combination of: a plate, an arm projecting from and adjustablelengthwise:of said plate, a bearing-block adjustable on said arm towardand from. said plate in a plane parallel withthe plane of said plate, and a marking devicecarried :by said, bearing-block and: adjustable transversely of the plane of said plate, and having. a" marking portion which extends in adirection substantially parallel with the plane of said plate, substantially as set-forth.

5. Thecombination of aplate, a bearingblockmovable relative to said plate, .means for securing said block in adjusted positions, a marking device carried by said block and movabletransversely of the direction of movement of the block; a nut for adjusting the marking device, and a nut for securing the latter in adjusted positions; substantially as set forth. 7
